What is the difference between Local Storage and SAN Storage?

A Storage area network, or SAN, is a high-speed network of storage devices that also connects those storage devices with servers. It provides block-level storage that can be accessed by the applications running on any networked servers. In our environment all data that is stored on a SAN is replicated every 3 hours to a second SAN at another location. This makes offering a redundant services at a second location in the event of an emergency or location disaster.

Local storage utilizes host server resources and NAS technology for backups. There is no redundant offering with local backups. If a location disaster were to occur then all information will be inaccessible until the issue is resolved. If the disaster results in the destruction of equipment then there is the possibility of permanent data loss.

Why is there such a big price Difference?

SAN technology is costly, it utilizes fast high end hard drives, has its own build in redundancy in the event that a drive dies. Also to provide redundancy replication needs to occur many times a day to our secondary location which requires a large amount of bandwidth.

What are the advantages of having a server on the SAN?

The primary advantage to being on the SAN is having built in disaster recovery

What are on-site and off-site backups?

Quite literally on-site backups means that the data is duplicated and stored at the same physical location as the live environments. Off-site backups means that the data is duplicated and stored at a separate physical location. For example a server in Brampton will have its backups in Toronto if it is an off-site backup. If it is an on-site backup both the server and the backup exist at the same Brampton datacenter but not on the same hardware.

What is a disaster recovery?

Disaster recovery (DR) the process, policies and procedures that are related to preparing for recovery or continuation of technology infrastructure which are vital to an organization after a natural or human-induced disaster. Disaster recovery focuses on the IT or technology systems that support business functions, as opposed to business continuity, which involves planning to keep all aspects of a business functioning in the midst of disruptive events.

Do I need Off-Site backups?

The answer to this depends on how you answer the question, "can I afford to permanently lose my data". Data is stored on multiple pieces of hardware in a single location and it is extremely unlikely that they would all fail at the same time. So permanent loss of data is not a likely event in most cases. However, location specific problems such as fire, water electrical damage, natural disaster and acts of terrorism can cause widespread loss of data. Off-Site backups are a way of ensuring that a single widespread event does not destroy all company data. It is recommended that anyone who cannot afford to lose company data and start from scratch consider off-site backups.

Do I need disaster recovery?

The answer to this depends very much on your answer to "how long can you afford to be down?" If a server or datacenter were to go off line and it were to take 24-48hours to be recovered can you afford to be down that time. If you answer is yes then you do not require disaster recovery. If the answer is no and you feel that in the event of such a disaster a few hours is all you could afford to be down then you should consider a hosting package that includes disaster recovery.

What is a Plesk control Panel?

Parallels Plesk Panel allows a server administrator to set up new websites, reseller accounts, e-mail accounts, and DNS entries through a web-based interface. The administrator can create client and site templates, which predetermine resource-allocation parameters for the domains and/or clients.

Why would I want to add Plesk to a VPS?

Plesk allows you to manage access for multiple users via a web control panel interface for services such as ftp, email, sql and IIS. As well Plesk can track resource usage (disk space, bandwidth) on a per site/user basis.
